Sure you can put mass around your stove to help hold the heat.
I suggest stacking clay brick on 3 sides , as thick and tall as you like. Mortared or dry stack...

Gerry Parent wrote:Hi Gabe, Your metal woodstove was designed to mostly radiate heat away from it - This is so that the metal stays intact without prematurely breaking down or warping. If you were to add too much mass right up against the stove this may happen. Capturing the radiant heat with a gap though is a great idea, but a rocket mass heater would be even more great! Lots of rocket scientists to help you out here :D

I second Gerry in leaving a gap between the stove and mass...

David Baillie wrote:Hi gabe. I see an eco fan on top do you have a hole in the back cowling for a blower? You will get significant increases of heat off the stove with it. If not get a box fan and mount it behind it on low. Push that heat at the drywall walls and let them act as your mass...
Davis Tyler wrote:what's the main problem with your existing stove? Just the daily temperature swings? How long does a load of dry firewood last? What sort of high and low temperature do you see in the stove room throughout the day?
How many cords of wood do you burn in a typical winter?
There are efficient catalytic and secondary-burn stoves that even out the temperature swings. They're not cheap. I load my Blaze King 2x a day all winter long (3x a day if the night drops into single-digits). It keeps the house between 65-72 degrees 24/7. I burn 3-4 cords of hardwood most winters.
The cheapest long-term solution is to improve the insulation and air-sealing of the house. There's a lot of low-hanging fruit for improvement in most cold-climate houses.

Yes, red clay bricks definitely have enough mass.
They are used in masonry stoves and more important in a rocket mass heater that utilizes a vertical brick bell.

i am pretty sure that the 'fire' bricks that are used in rocket mass heater applications are special purpose. they are larger and much lighter than the other more common types.

In a previous home we had built a "real" masonry wood heater, complete with a warming bench, a puzzle chamber of flue paths, the whole 9 yards. The current hybrid stove works as well and was waaaay easier to construct.

I didn't do it. You can't prove it. Nobody saw me. The sheep are lying! This tiny ad is my witness!
